我应该怎么做才能解决这个错误？\n谢谢

Answer 1

确保您已安装 psycopg2 所需的系统依赖项。在 Ubuntu 或 Debian 上，您可以运行以下命令来安装它们：

sudo apt-get install libpq-dev python3-dev

然后依赖安装成功后再次运行安装。

pip install psycopg2

Answer 2

您应该只拥有其中之一

psycopg2 = "^2.9.5"
psycopg2-binary = "^2.9.5"

不是都。

psycopg2 = "^2.9.5"尝试从 pyproject.toml 文件中删除。

Answer 3

为我解决的是：apt install libpq-dev gcc
